Installation patterns for terrace slabs
The right installation pattern is crucial for the stability and appearance of your terrace. Here are the two most popular options:
Grid pattern
In the grid pattern, slabs are laid so that the joints form continuous straight lines, both horizontally and vertically. Advantages:
- Very stable
- Even load distribution
- Clean, organized appearance
Half bond (brick bond)
In the half bond (also called brick bond), every row is offset by half the slab length. Advantages:
- Modern, dynamic appearance
- Improved load distribution
- Ideal for slip-resistant surfaces
What types of terrace supports exist?
There are different support types used for building a stable terrace, depending on the base layer:
- Gravel supports – Ideal for terraces on gravel or crushed stone, provides good drainage.
- Slab supports – Perfect for quick installation of terrace slabs.
- Flat slab supports – Especially low-profile, ideal for low installation heights.
- Pedestal supports – Height-adjustable, suitable for uneven surfaces.
- Adjustable pedestal supports – Allow slope compensation; perfect for sloped terraces.
- Adjustable slab supports – Height compensation for maximum flexibility during terrace installation.
